This is a mostly forgotten TV special produced by Lorne Michaels and features some cast members and several writers from the 70's era of SNL. I suppose it is mostly remembered now for having John Belushi giving his last ever performance (released anyway) as the long lost sister to Aykroyd and Martin's "Wild and Crazy Guys".
Dan Aykroyd is in alot of the scenes. Bill Murray turns up, Lorraine Newman too, but it isn't the best written comedy show. A filmed scene with Eric Idle I believe originally aired on his British show Rutland Weekend Television (WORTH SEARCHING OUT BTW) is used. The only live part of this I actually enjoy is the song and dance number Martin does with Gregory Hines. The rest is fairly forgettable.
